Description

technical field

[0001] The invention relates to a mold assembly method, in particular to a mold core-in-sub assembly method. Background technique

[0002] With the continuous development of science and technology, portable electronic devices, such as mobile phones, are widely used and tend to be lightweight, beautiful and multi-functional. Among them, the camera function is an additional function of the newly developed portable electronic device in recent years. Mobile phones with digital cameras are more and more favored by users because they can realize the instant shooting function and are easy to use. Due to the small volume of the mobile phone, the camera module installed in the mobile phone needs to have a small volume. While people are pursuing the miniaturization of digital camera modules for mobile phones, they also put forward higher requirements for its imaging quality. The imaging quality of objects depends to a large extent on the quality of the optical lenses...
